Backend API. Server-side code: this runs in a Codename One backend, not in the app on the device.

public interface TaskDecorator

Wraps every task an executor runs, as Spring’s does: the place to carry something from the submitting thread – a tenant, a trace, a security principal – to the one that runs the task, and to clear it afterwards.

Tasks.executor("mail").setTaskDecorator(new TaskDecorator() {
    public Runnable decorate(final Runnable task) {
        final String tenant = Tenant.current();
        return new Runnable() {
            public void run() {
                Tenant.set(tenant);
                try {
                    task.run();
                } finally {
                    Tenant.clear();
                }
            }
        };
    }
});
